This is 4-Pack compatible / remanufactured Brother TN760 toner cartridges. Each toner cartridge is manufactured to be comparative to the original in terms of quality and page yield. Extensive testing and R&D have enabled us to produce cartridges that will not only save you money, but also provide a high quality product to ensure long term customer satisfaction.
IMPORTANT: These are compatible cartridges that come without a chip. You need to move the chip from your original (OEM) cartridge and place it onto the compatible cartridges (the same chip can be re-used many times). This means that the printer will show "empty" or "0" toner supply due to the used chip, but the cartridges will still be able to print for the full life cycle and you can bypass the supply message that will popup by following the simple instructions included. Print yield or print quality will not be affected. Transferring the chip is easy to do and takes 5 seconds, instructions included, which will make it easy for you to move the chip from your original cartridge to this compatible cartridge. The chip can be re-used many times.
NOTE: You must have a chip from an original Brother cartridge to transfer to these compatible cartridges (easy to do, instructions included, chip can be reused many times). Any original cartridge will have this chip except for STARTER cartridges which are the ones you get when you first buy the printer.
